Product Description

The following are the core physical parameters of the Hex Flange Head Self Tapping Concrete Anchor Bolt from supplier Xiaoguo®, applicable to common specifications ranging from M6 to M16.

（1）Nominal diameter and length range

Nominal diameter (d)	Common length (L)	Effective thread length	Head height	Flange diameter
M6	40,50,60,70,80,100mm	≈L-10mm	4.5-5.0mm	12-13mm
M8	50,60,70,80,90,100,120,150mm	≈L-12mm	5.5-6.0mm	16-17mm
M10	60,75,80,90,100,120,150mm	≈L-15mm	7.0-7.5mm	19-20mm
M12	80,100,120,150,180,200mm	≈L-18mm	8.5-9.0mm	22-24mm
M16	100,120,150,180,200mm	≈L-22mm	11-12mm	28-30mm

If the length exceeds 200 mm, we can customize it, but the anchoring depth needs to be re-verified.

Stainless steel A2	304	45-50	25-30	Natural passivation, electrolytic polishing
Stainless steel A4	316	45-50	25-30	Original color passivation

Hex Flange Head Self Tapping Concrete Anchor Bolt

The benefits brought by structure

Not by expanding the pipe, but by the threads self-engaging - The structural highlight of the Hex Flange Head Self Tapping Concrete Anchor Bolt.The anchor bolt looks like a super-large screw, but it is completely different from ordinary expansion bolts.

（1）Built-in gasket + teeth

The flange of the Hex Flange Head Self Tapping Concrete Anchor Bolt is an integral formed gasket and will never come off.Under the flange, there is also a ring of small teeth. When tightened, they will penetrate into the steel plate or gasket, and will not loosen during the operation of the machine.

（2）The threads are as hard as a knife.

The threaded part that has undergone surface hardening is as hard as a chisel.Push it into the pre-drilled hole. The blade on the threaded side will scrape the concrete to create the matching internal thread, and then it will securely grip.It doesn't expand outward to push apart. Instead, it relies on the interlocking of threads, so it won't crack the concrete.

（3）Full thread

From the bottom of the flange all the way up to the tip, it is entirely threaded.The deeper it is screwed, the longer the length of the thread that bites into the concrete, and the stronger the uplift resistance will be.

（4）Sharp-pointed guidance, no deviation

At the end there is a small conical tip, resembling a pilot drill.After being placed in the hole, the pointed end presses against the bottom of the hole, ensuring that the Hex Flange Head Self Tapping Concrete Anchor Bolt is perpendicular to the wall surface and won't be tilted when being tightened.

（5）Support for repeated use

If any problem occurs, this anchor bolt can be completely removed using a wrench, repositioned and then reinstalled. It is particularly suitable for situations where the bolt needs to be disassembled and reassembled multiple times.
